It is the legislative intent that small communities have the power to issue municipal revenue bonds for the purpose of constructing office facilities for physicians as a method of attracting physicians. Therefore, for the purposes of Sections 3-32-3, 3-32-5 and Subsection F of Section 3-32-1 N.M. Stat. Ann., “small municipality” means an incorporated municipality having a population of less than fifteen thousand as shown by the last preceding official United States census. For limited purposes stated in this section, physicians offices are allowed even though the physicians operate as a profit- making enterprise.
